Concentric Reducer Concentric VS Eccentric

45in BW reducer is belong to large dimension butt welded fittings,STD is a commonly used wall thickness for BW fittings.Other commonly used wall thicknesses for BW fittings are SCH 40,SCH 80.

Long radius elbow refers to the pipe outer diameter with radius of curvature equal to 1.5 times, i.e R = 1.5D. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

Long Radius (LR) Elbow is also called LR elbow – means the radius is 1.5 times the pipe diameter
L/R 45°Elbow: Long radius 45 degree elbow changes the direction by 45 degrees.
L/R 90°Elbow: Long radius 90 degree elbow changes the direction by 90 degrees.
L/R 180°Elbow: Long Radius 180 degree return bend allows complete reversal of flow.

According to its radius of curvature, it can be divided into long radius elbow and short radius elbow. Long radius elbow means that its radius of curvature is equal to 1.5 times the outer diameter of the pipe, that is, r = 1.5D. Short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, r = 1.0d.

Elbow is a pipe fitting that changes the direction of piping. According to the Angle, there are 45° and 90°180° three most commonly used. Elbow material can be divided into carbon steel, alloy steel and stainless-steel.

ASTM A234 specification has many grades, such as WPB, WPC, WP5, WP9 WP11, WP12, WP22, WP91 and so on.
In these standard Grade WPB is the most common material used for medium and high temperature pipelines. W means weldable, P means pressure, B is grade b, refer to the minimum yield strength.

Stainless 316L tee is a stainless steel pipe fitting used to change the direction of the fluids or gas and branch the pipe system.Tees can be equal tees and reducing tees for different usages.Stainless steel fittings are be chosen by the long using years.Beacuse of the high corrosion resistance,stainless steel can be used over 50 years.

Concentric reducers are tapered and are used when the diameter between pipes changes. It can be axially shifted and externally reconfigured to offer more efficient reducer connection.

45 deg elbow is a type of elbows,there are also 90 deg elbows and 180 deg elbows.These elbows have similar functions,the main difference is the degree.Elbows can be BW,SW and THD to chosen for different applications.Shanghai Zhucheng is a quality pipe fittings supplier from China.

ASTM A234 WPB Butt Welded Fittings are the best selling products in Shanghai Zhucheng Pipe Fittings Manufacturing Co Ltd from China.We can also supply customers forged pipe fittings,pipes and some related products.

Concentric reducer is used to join pipe sections or tube sections on the same axis. It is cone-shaped, and is used when there is a shift in diameter between pipes. 

ASME B16.9 butt welded fittings are American Standard BW fittings.COC Reducer means concentric reducer,BW reducers can be concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.

Classify,specification of a BW 90 degree elbow

Butt weld fittings include elbows, tees, cross, caps and reduces. These fittings are the most common type of welded pipe fitting and are specified by nominal pipe size and pipe schedule. Buttweld fittings are manufacture by seamless or welded pipe and are formed to get the shape of elbows, tees and cross etc.

he pipes cannot appreciate because of what the external arrangement of the pipe reducer seems but the flow of the pipe is changed by the internal width conical transition arrangement.

classification,dimension of lateral tee,and its difference from a WYE.

Elbows and seamless elbows are often used in the bending parts of pipes to change the direction of pipes Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

The connection methods of elbow and pipe include: direct welding (the most common method), flange connection, hot melt connection, electric fusion connection, thread connection and socket connection

Butt weld fittings are manufacture by seamless or welded pipe. For pipe fittings manufacturers, the forming process of welded pipe and seamless pipe is basically same. Butt welded fittings can be divided into carbon steel butt welded fittings and stainless-steel butt-welded fittings

When short radius elbows are used, the maximum working pressure should not exceed 0.8 times of long radius elbows of the same specification Miter elbows are usually used for large-size pipes with moderate conditions in low pressure (design pressure s2.0mpa), water and similar fluid media

Carbon steel butt welding 90 degree elbow is a connector specially designed for use in piping systems. Its main function is to create a 90 degree turn in the pipe so that the fluid can flow along a predetermined path.

BW 90 degree elbow is the most chosen type in all types of elbows.It can be long radius (LR) or short radius (SR).ASTM A234 WPC is standard for carbon steel butt welded fittings.There is also a more commonly used standard for carbon steel butt welded fittings is ASTM A234 WPB.

Connect two pipes with the same or different nominal diameters to make the pipeline turn at 90 degrees, 45 degrees, 180 degrees and other angles

ASME B16.9 elbow means BW elbow.ASME B16.9 is an American Standard for Butt welded fittings,A234 WP22 is represnets BW Alloy pipe fittings. Elbows can be 90 deg and 45 deg to change the pipes in 90 degree or 45 degree.Sometimes the elbows can be 180 deg to satisfy the clinet’s demands.
